Upon the treatment of bis(arylcarbonyl)diphenylacetylenes with lithium naphthalenide, the carbonyl reduction dominantly occurs over the acetylene reduction. The produced bis(radical anion) intermediate undergoes a synchronous double-radical 5-endo-dig cyc

(Chemical Equation Presented) Facile photochemical exocyclic [2 + 2 + 2] cycloaddition produced a series of electron-donating 1,1′- bi(isobenzofuran)s having various aryl groups at the 3,3′ positions. The 1,1′-bi(isobenzofuran) skeleton with a highly coplanar structure is a useful building unit to construct the narrow bandgap π-conjugated systems with low oxidation potentials.
